Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the preparation of active ingredients requiring brominated aromatic scaffolds. Its carboxylic acid functionality allows for easy derivatization, making it valuable in coupling reactions for drug development. Also employed in the production of specialty organic compounds where the bromine atom serves as a site for further functionalization via cross-coupling reactions such as Suzuki or Heck reactions. Its ethyl group contributes to lipophilicity, which can influence the biological activity and pharmacokinetics of resulting compounds.
